EDGE GAUGE AND SHOE GUARD.

Application filed November 7, 1921. Serial No. 513,411.

To all whom it may concern:

Be it known that I, LE0 SOHILDKNECHT, a citizen of the United States, residing at St. Louis, Missouri, have invented a cer tain new and useful Improvement in Edge Gauges and Shoe Guards, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this application.

My invention relates to shoe stitching machinery and consists in an improved device for guiding the edge of the welt or sole or both at the needle and awl and guarding the shoe from the needle and awl and adjacent moving elements of the machine. 7

It is customary in shoe stitchers to provide an adjustable edge gauge which may be moved on its mounting to accommodate different widths of welts, different locations of the stitching through the welt, or different thicknesses of the sole. This gauge is usually so positioned in front of the awl that in order to replace the awl, the gauge must be removed from the machine. It is frequentlynecessary to change the awls due to breakage or other reasons and when this is done, the removal and re-- placement of the gauge and the adjustment of the latter consume considerable time. A guard for'the shoe upper is ordie narily provided near the above-mentioned partsand is usually necessary when an awl is replaced to remove the shoe guard also, although the lack of adjustment of the latter may not require as much time for its removal and replacement as required for the same manipulation of the gauge.

The object of my invention is to eliminate this loss of time and possibility of inaccurate adjustment by providing a gauge and guard so mounted upon the machine that they may be easily swung into and out of operative position without losing the adjustable feature heretofore possessed by these members.

of the shoe stitcher to which my invention applies and showing the edge gauge and shoe guard in normal operative positionand in temporary inoperative position.

Figure 2 is a side view of the elements shown in Figure 1, looking from the right.

A portion of the machine frame is indicated at 1 and upon this is fixedly secured an upright element 2 having a lateral projection An armd is pivotally mounted upon upright 2 by means of a screw 5 extending through a bushing 6 in arm 4 and threaded into upright 2. A spring washer 7 under the head of screw 5 createssuflicient friction between arm 4 and upright 2 to yieldingly hold the arm in any. posi: tion to which it may be rotated.

Arm a is provided with a projecting toe 8 which, whenthe arm is in upright position as shown by solid lines in Figure 1, engages the end of a-screw 9 extending through projection 8 of upright 2 and locked by jam-nut 1.0. These parts serve to limit the movement of arm 1 to the left about its pivot. An edge gauge 11 of the usual type is carried by arm at and is assembled therewith by means of screws gauge. Slots 13 provide for vertical adjustment .of the gauge on the arm and screw 9 provides for lateral adjustment of the gauge relative to the machine awl 14.

A shoe guard 15 is mounted on arm 4: and held in place by screw 5 and a suitable pin 16. The opening in the guard 15 for the screw 5 is somewhat larger than the diameter of the screw and the opening for pin 16 is elongated, whereby slidable adj ustment of guard 15 is provided on arm 4:.

The pivotal mounting of arm 4 which carries gauge 11 and guard 15 enables the operator to instantly rotate the gauge and guard from the operative position to the inoperative position indicated by dot-anddash lines in Figure 1. In the latter position, the gauge and guard are removed from the awl and will not interfere with the operation of a wrench 17 which is used to loosen the awl clamp nut 18.

lVhen the awl has been adjusted or replaced, the gauge and guard may be instantly swung up and to the left to their operative position without any necessity of adjusting or clamping.

My device greatly facilitates the operation of the machine referred to. To secure the same results with the previous arrangev 12 which extend through slots 13 in the,

Inents, it is necessary to remove one or more screws holding the guard in position and the two screws holding the gauge in position. Not only must .these screws .be removed and reinserted after replacement of the awl, but the adjustment of the gauge must be taken care of each time.

The advantages of the use of my device will be apparent to those skilled in the art, and the construction shown will suggest various modifications which may be made without departing from the spirit of my invention, as expressed in. :the following. claims:

I claim:

1. In a shoe stitcher, a stitoher tool, an edge gauge, a shoe guard, and a pivot carrying said guard and gauge about which they may be moved a unit into and out of operative position.

2. In a shoe stitcher, a stitcher .tool, a member pivotally mounted upon the stitcher, an edge gauge and a shoe guard carried by said member and adapted .to be moved there with about the pivot of the latter to and from operative position.

,3. In a shoe stitcher, a stitcher tool passing'rthrough :theshoe sole, an edge gauge, a shoe guard, and means for moving said gauge and guard into and outof normal operative position irrespective of the. position of said tool.

4t. In A-Sl106 stitcher, a stitcher tool passing through the shoe sole, .an edge gauge and a shoe guard adjustable relatively to each other, and means for moving said gauge and guard as a unit into and out of normal operative position irrespective of the position of said "tool.

In a shoe stitcher, a stitcher tool, a member pivotally mounted upon the stitcher, and a shoe guard and anedge gauge each adjustabl y supported by said member and movable with said member about its pivot.

6. In a shoe stitcher, a movable tool passing through the shoe sole, a pivot element,

and shoe guiding means car 'ried by said element so as to be swung in an are about the same into posltion ad acent to said tool to determine the position of the shoe relative from said position :to permit free access .to'

the tool, an adjustable member for limiting the pivotal movement of said meansinto functioning posrtron, and frictlon elements for yieldingly retaining said :member in said position.

8. In a shoe stitcher, a stitcher tool, tool securing .means, a shoe gauge member nor-- mally preventing access ;to said .means and pivotally mounted upon the st-itcher .to swing in an are about its pivot toward and away from the tool .into and .outozt operative position respectively, and adjustable means for limiting the movement of said member when the latter is rotated to said operative position.

9. In a shoe stitcher, a stitcher :tool, a tool clamping .nut, a shoe gauge normally positioned in front of said nut and preventing access thereto, an arm upon which said gauge is fixedly mounted, and apivot bearing for, said .arm about which it may be turned, irrespective of the position of said pivot bearing, to swing said gauge :to a position in which it permits access to said nut. v

In testimonyv whereof 'I hereunto aflix my signature this 31st day of October, 1921.
